Description

Technical Field

[0001] The present invention belongs to the field of industrial automation control systems and relates to a DCS controller network connection verification method, system, equipment and storage medium. Background Art

[0002] In industrial automation control systems, DCS (Distributed Control System) controllers are the cornerstone of core industrial facilities such as power plants and chemical plants, and their importance is self-evident. These advanced controllers are not only closely connected to the host computer configuration tools through the network architecture, realizing seamless docking of remote control and management, but also undertake multiple tasks such as downloading precise control logic, real-time monitoring of operating status, and efficient fault diagnosis. This powerful interconnection capability has greatly improved production efficiency and safety.

[0003] However, while pursuing efficiency and convenience, the existing DCS controller network connection verification mechanism exposes potential risks. Current verification methods often only focus on the initial stage of connection establishment, that is, ensuring that the upper and lower computers can successfully handshake and communicate, but ignore the in-depth verification of connection consistency. This approach of focusing on establishment and neglecting verification leaves room for human error. Once an unmatched or inconsistent connection is established between the upper and lower controllers due to operational errors, the robustness of the entire system will be severely challenged.

[0004] What’s more serious is that inconsistent connections may trigger a series of chain reactions. The lower-level controller may fail to accurately parse the control instructions from the upper-level configuration tool, resulting in deviation or failure of the control strategy execution. This deviation will not only cause fluctuations in the production process and reduce efficiency, but is also more likely to trigger safety alarms, cause equipment shutdowns, and even cause more serious production accidents. In extreme cases, the lower-level controller may fall into a state of confusion due to receiving erroneous instructions for a long time, and eventually crash, posing a fatal threat to the safe and stable operation of key industrial facilities such as power plants and chemical plants. Therefore, strengthening the consistency verification of DCS controller network connections has become a top priority to ensure the safe operation of industrial automation control systems.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0031] See also Figure 1 In one embodiment of the present invention, a DCS controller network connection verification method is provided to ensure the security of the connection through strict information verification and prevent safety accidents caused by inconsistent controller information.

[0032] Specifically, the DCS controller network connection verification method of the present invention includes the following steps:

[0033] S1: The upper computer configuration tool sends a connection request to the lower computer DCS controller; wherein the connection request is used to trigger the lower computer DCS controller to send verification information to the upper computer configuration tool.

[0034] S2: The upper computer configuration tool receives and verifies the verification information in a comparison manner according to the preset controller configuration information, and obtains the verification result of the lower computer DCS controller.

[0035] S3: When the verification results of the lower-level DCS controller are consistent, a network connection is established between the lower-level DCS controller and the upper-level configuration tool.

[0036] The DCS controller network connection verification method of the present invention first sends a connection request to the lower-machine DCS controller through the upper-machine configuration tool, triggering the lower-machine DCS controller to send verification information to the upper-machine configuration tool, and then the upper-machine configuration tool receives and verifies the verification information according to the preset controller configuration information by a comparison method, obtains the verification result of the lower-machine DCS controller, and when the verification result of the lower-machine DCS controller is consistent, establishes the network connection between the lower-machine DCS controller and the upper-machine configuration tool. Through strict information verification, it is ensured that the connection between the upper-machine configuration tool and the lower-machine DCS controller is safe and reliable, and the connection is allowed only when the verification is passed, thereby ensuring the safety of the connection and avoiding the situation that the connection is established due to the inconsistency of the upper and lower-machine controller information, thereby causing a safety accident in production. At the same time, the automated information acquisition and verification process reduces the user's operating difficulty and complexity, and verification is performed before the connection is established, ensuring the stability and reliability of the system, and can be applied to various models of DCS controllers, with wide applicability and promotion value.

[0037] Among them, the lower-level DCS controller is a physical controller.

[0038] In a possible implementation manner, the verification information includes a controller model, a controller type, and an algorithm library version.

[0039] Specifically, the design of verification information does need to be detailed and specific to ensure the compatibility and security of the system or device. The combination of controller model, controller type and algorithm library version is used to ensure the security of subsequent connections. Among them, controller model: The controller model is a unique identifier to identify a specific hardware device. Different controller models may have different hardware configurations, performance parameters and interface standards. By verifying the controller model, the system can ensure that the connected controller is the expected device, thereby avoiding problems caused by hardware mismatch. Controller type: The controller type usually refers to the classification or functional category to which the controller belongs, such as motion controller, process controller or other type of controller. This classification helps the system quickly identify the basic functions and uses of the controller, so as to adopt corresponding processing strategies or configure corresponding parameters. Algorithm library version: The algorithm library version refers to the version number of the software or algorithm set running on the controller. The algorithm library contains program code that implements specific control logic and functions. Different versions of the algorithm library may contain different functions, performance optimizations or security fixes. Verifying the algorithm library version can ensure that the software running on the controller is compatible with the rest of the system and has the latest security features and performance optimizations.

[0040] In a possible implementation, the preset controller configuration information is obtained by creating and configuring a controller in a host computer configuration tool according to actual requirements, and recording the controller model, controller type and configuration tool algorithm library version of the controller as controller configuration information.

[0041] Specifically, in the upper computer configuration tool, a controller is created and configured according to actual needs, and key information such as the controller model, controller type, and configuration tool algorithm library version of the controller is recorded in detail to serve as the preset controller configuration information to realize the comparison and verification of the verification information sent by the lower computer DCS controller.

[0042] In a possible implementation, the verification information is verified by comparison according to preset controller configuration information to obtain the verification result of the lower-level DCS controller, including: obtaining the controller model, controller type and configuration tool algorithm library version in the preset controller configuration information, and the controller model, controller type and algorithm library version in the verification information; when the controller model in the controller configuration information is consistent with the controller model in the verification information, the controller type in the controller configuration information is consistent with the controller type in the verification information, and the algorithm library version in the verification information is compatible with the configuration tool algorithm library version in the controller configuration information, the verification result of the lower-level DCS controller is consistent; otherwise, the verification result of the lower-level DCS controller is inconsistent.

[0043] Specifically, the preset controller configuration information created in the upper computer configuration tool is compared and verified with the verification information sent by the lower computer DCS controller extracted from the network connection information. Optionally, the comparison and verification is carried out in the manner and order of whether the controller model is consistent, whether the controller type is consistent, and whether the algorithm library version is compatible. Only when the controller model is consistent, the controller type is consistent, and the algorithm library version is compatible, the verification result of the lower computer DCS controller is considered consistent. At the same time, according to the verification result of the lower computer DCS controller, it is automatically determined whether to allow the establishment of a network connection. If all the check items pass, that is, the verification result of the lower computer DCS controller is consistent, the connection is allowed to be established; if any of the checks fail, that is, the verification result of the lower computer DCS controller is inconsistent, the connection is rejected.

[0044] In a possible implementation manner, when the verification result of the lower DCS controller is inconsistent, verification error information is generated.

[0045] Specifically, the generation of verification error information can immediately notify the system or operator of the current problem, which helps to quickly respond to and solve the problem and prevent the problem from further deteriorating or affecting the normal operation of the system.

[0046] In a possible implementation, the verification error information includes: a comparison result between the controller model, controller type and configuration tool algorithm library version in the controller configuration information and the controller model, controller type and algorithm library version in the verification information.

[0047] Specifically, the verification error information includes specific comparison results, which can enable operators to understand specific problems in a timely manner so as to carry out targeted processing.

[0048] Optionally, after the verification error information is generated, the verification error information may be visually displayed.

[0049] See also Figure 2 In a possible implementation manner, the DCS controller network connection verification method specifically includes the following steps:

[0050] Step 1: In the host computer configuration tool, create and configure the controller according to actual needs, and record the controller model, controller type, and configuration tool algorithm library version of the controller as the controller configuration information.

[0051] Step 2: The host computer configuration tool sends a connection request to the lower computer DCS controller.

[0052] Step 3: The lower-level DCS controller receives the connection request and returns its own controller model, controller type, algorithm library version and other actual information.

[0053] Step 4: Use a comparison method to check whether the controller model in the preset controller configuration information is consistent with the controller model in the verification information; when the controller model in the preset controller configuration information is consistent with the controller model in the verification information, proceed to step 5; otherwise, the verification result of the lower-level DCS controller is inconsistent, and it is not allowed to establish a network connection between the lower-level DCS controller and the upper-level configuration tool, and a verification error message is generated.

[0054] Step 5: Use a comparison method to check whether the controller type in the preset controller configuration information matches the controller type in the verification information; when the controller type in the preset controller configuration information matches the controller type in the verification information, proceed to step 6; otherwise, the verification result of the lower-level DCS controller is inconsistent, and it is not allowed to establish a network connection between the lower-level DCS controller and the upper-level configuration tool, and a verification error message is generated.

[0055] Step 6: Use a comparison method to check whether the configuration tool algorithm library version in the preset controller configuration information is compatible with the algorithm library version in the verification information; when the configuration tool algorithm library version in the preset controller configuration information is compatible with the algorithm library version in the verification information, and the verification result of the lower-level DCS controller is consistent, a network connection between the lower-level DCS controller and the upper-level configuration tool is established; otherwise, the verification result of the lower-level DCS controller is inconsistent, and the network connection between the lower-level DCS controller and the upper-level configuration tool is not allowed to be established, and a verification error message is generated.
